The component of the apparatus and the test method of different types of bitumen viscosity are described below based on IS 1206 parts I, II, and III: 1. Industrial, dynamic, and kinematic viscosity tests according to IS 1206 method I, II, and III are described as follows: Viscosity Test of Bitumen Based on IS 1206 The following standard methods can be used to determine the viscosity of bitumen: Different Methods for Viscosity Test of Bitumen in International Standards Therefore, the kinematic viscosity is measured at 135 ☌. Furthermore, it measures the resistance of bitumen to melt and flow.Īt higher temperatures, bitumen viscosity measurements are necessary to better understand its ability to coat aggregates well. Because the softening point test is directly related to the viscosity property.

As a result, we can predict the best temperature that bitumen should mix and compact.Ībsolute or dynamic viscosity at 60 ☌ is measured to indicate the resistance of bitumen to melting and flow.Īlso, this test can be a substitute for the softening point test. For this reason, engineers measure the viscosity of bitumen at two different temperatures of 60 ☌ and 135 ☌. Viscosity is a property that is affected by temperature changes. Consequently, it is important to choose a bitumen with a suitable viscosity. Moreover, compacting aggregates is difficult with a high viscosity bitumen binder thus, asphalt will not be uniform. Low viscosity bitumen tends to flow and behave like a lubricant and not a binder, so it cannot adhere to aggregates well. Viscosity is a good property to show the ability of bitumen in coating and adhesion. This is gained when the aggregates are well-packed and the space between them is filled well. The aim of standard construction is to have a uniform and stable asphalt. Why Do We Use the Viscosity Test of Bitumen? The Procedure of Kinematic Viscosity Test of Bitumen: Equipment to Measure the Kinematic Viscosity: The Procedure of Dynamic Viscosity Test of Bitumen: Equipment to Measure the Dynamic or Absolute Viscosity: The Procedure of the Industrial Viscometer Test

Viscosity Test of Bitumen Based on IS 1206.

Different Methods for Viscosity Test of Bitumen in International Standards.

Why Do We Use the Viscosity Test of Bitumen?.

Here is an example of the viscosity value of viscosity bitumen grades based on IS 1206 method parts II and III: Viscosity Value of Viscosity Bitumen Grades The bitumen viscosity unit is based on mm 2/s. In general, to perform the viscosity test of bitumen, the sample is placed in the viscometer then the flow-out time of bitumen is measured under specified conditions. Finally, the amount of viscosity is determined by multiplying the calibration coefficient of the viscometer by the flow time in seconds.

Kinematic viscosity => It is measured by different types of capillary viscometers.

Dynamic/Absolute viscosity => It is measured by different types of vacuum capillary viscometers.

Industrial viscosity => The dynamic viscosity which is measured by the cup viscometer is called industrial.

Consequently, it behaves more like semi-solid matter.īitumen viscosity is determined by viscometers. In the following video, our team at Infinity Galaxy shows how rotary and capillary viscometers are used to measure dynamic (ASTM D4402) and kinematic (ASTM D2170 or IS 1206) viscosity of bitumen.īelow is a list of different ways of specifying viscosity and measuring it based on the Indian bureau standard definition: The higher the viscosity of the bitumen, the harder it is to flow. This property shows how easily bitumen flows.

The viscosity test of bitumen measures the bitumen viscosity.
